Title: Control method for multi-cylinder internal combustion engine and electronic control device therefor
Inventor: NAGANO MASAMI
IPC: F02P5/15
Filed: 1988-10-17
Abstract: PURPOSE:To obtain stable engine output by estimating combustion pressure of each cylinder via the detection of an engine speed in the combustion stroke of each cylinder of a multi-cylinder internal combustion engine, obtaining a combustion pressure deviation between each cylinder and adjusting ignition timing for each cylinder depending upon the deviation. CONSTITUTION:During the operation of an engine 7, a control unit 15 reads basic ignition timing and basic fuel injection intervals from a memory map on the basis of an engine speed, based upon output from a crank angle sensor 155 and an air flow meter 3. Also, the average of engine speeds is obtained and concurrently the speed of a corresponding cylinder is compared with the average, thereby obtaining an engine speed deviation. Then, it is judged whether the deviation is positive or negative, and the deviation is compared with the predetermined value. According to the result of the comparison, an abnormal value judgement counter is controlled. When the absolute value of a reading from the counter is larger than the predetermined value, the combustion condition of a corresponding cylinder is judged to be abnormal. Upon the judgement of abnormality, an air-fuel ratio is corrected.
